Podophyllotoxin is a naturally occurring compound derived from the roots and rhizomes of the Podophyllum plant, commonly known as Mayapple. It is a member of the lignan family and is primarily used for its cytotoxic properties. Podophyllotoxin serves as a precursor for the synthesis of several anticancer drugs, such as etoposide and teniposide, and is also used in the topical treatment of genital warts.
